My Lockbox is a risky program to use and I just found this out the hard way. I used it for several months and everything seemed fine until it decided to update and then proceeded to wipe out everything it was hiding. I lost everything with this program so it's a good thing I had those files in another place. I would not trust any program where you are prompted to restart windows in order for it to work. There are two very good alternatives called PrivateFolder and Lock-A-Folder that are free, do not require a restart of windows, and are very safe to use.
